Abstract:

Background: Breech Presentation is the commonest of all malpresentations. Vaginal delivery of the breech presentations at term is associated with a much higher perinatal mortality and morbidity than that of vertex presentation. The objectives of the present study are to know the common causes leading to breech presentation. Further, to compare the different management protocols and outcome in different types of breech presentation. Also, to know the perinatal morbidity and mortality associated with different types of breech presentation nd comparison of perinatal morbidity and mortality with vaginal delivery against cesarean section.Methods: This is a retrospective study of randomized 100 cases of pregnant women in labour with breech presentations after 28 weeks or more attending C U Shah Medical College, Surendranagar, over a period of May 2012 to April 2014.Results: Out of 100 patients breech presentation was more common in booked patients and multigravida. In primi and multigravidae patients, caesarean delivery was more compared to assisted breech delivery. Perinatal outcome was good in majority of the patients in both extended and complete breech with an incidence of 94% and 88% respectively. perinatal outcome was good in caesarean section with 100% compared to assisted breech delivery 93%.Conclusions: The balanced decision about the mode of delivery on a case by case basis as well as conduct, training and regular drills of assisted breech delivery will go a long way to optimize the outcome of breech presentation like ours. Delivery of breech fetus when labor and delivery is supervised and or conducted by experienced obstetrician lowers maternal morbidity, neonatal morbidity and mortality.

Abstract:

IntroductionBreech presentation is a form of mal-presentation in which the fetal buttocks or lower extremities occupy or is in direct relationship with the maternal pelvic inlet. It is the commonest form of mal-presentation of the fetus. Its incidence decreases with advancing age from 25% at 28 Weeks, through 15% at 32 Weeks to 2-4% at term[1-3]. It accounts for 3-4% of infants born at term or at least 20,000 babies per year in the United Kingdom[3-5]. It is commoner in preterm babies and may be associated with both fetal and maternal anomalies. There has been intense debate about the safest mode of delivery for breech babies[5,6].Depending on the attitude of the fetus, breech presentation has been classified as:(a) Frank or Extended breech presentation when the fetal hips are flexed and the knees extended. It is also called 'pike'. This accounts for 50-70% of breech presentations and is commoner in Primigravidae;(b) Complete or Flexed breech presentation when both the hips and the knees are flexed. It is also described as 'cannon ball' and accounts for 5-10% of breech presentations. It is commoner in Multiparous women.(c) Footling or Incomplete breech presentation when one or both hips are extended. Here the foot (or feet) lies below the fetal buttock and either it or the knee(s) may be presenting[3,5,7].

Abstract:

Background The effect on neonatal mortality of mode of delivery of a fetus in breech presentation at an extremely preterm gestational age remains controversial. Objective To compare mortality associated with planned vaginal delivery (PVD) of fetuses in breech presentation with that of fetuses in breech presentation with a planned cesarean delivery (PCD). Material and methods Retrospective study reviewing records over a 19-year period in a level 3 university referral center of singleton infants born between 25+0 and 27+6 weeks of gestation, alive on arrival in the delivery room, and weighing at least 500 grams at birth. Infants in the first group were in breech presentation with PVD and the second in breech presentation with PCD. The principal endpoint was neonatal death. Results During the study period, we observed 113 breech presentations with PVD, and 80 breech presentations with PCD. Although not significant after adjustment, neonatal mortality in the breech PVD group was more than twice that of the breech PCD group (19.5 vs 7.8%, P = 0.031, ORa = 2.6, 95% CI 0.8–9.3, NNT = 8). This higher neonatal mortality in the breech PVD group was exclusively associated with a higher risk of death in the delivery room (12.4 vs 0.0% P = 0.001, OR not calculable, NNT = 8). In these extremely preterm breech presentations with PVD, neonatal mortality in the delivery room was associated with entrapment of the aftercoming head, cord prolapse, and a short duration of labor. Conclusion For deliveries between 25+0 and 27+6 weeks’ gestation, vaginal delivery in breech presentation is associated with a higher risk of death in the delivery room.

Abstract:

Objective Investigate maternal and neonatal outcomes associated with breech presentation in planned community births in the United States, including outcomes associated with types of breech presentation (i.e., frank, complete, footling/kneeling) Design Secondary analysis of prospective cohort data from a national perinatal data registry (MANA Stats) Setting Planned community birth (homes and birth centers), United States Sample Individuals with a term, singleton gestation (N = 71,943) planning community birth at labor onset Methods Descriptive statistics to calculate associations between types of breech presentation and maternal and neonatal outcomes Main outcome measures Maternal: intrapartum/postpartum transfer, hospitalization, cesarean, hemorrhage, severe perineal laceration, duration of labor stages and membrane rupture Neonatal: transfer, hospitalization, NICU admission, congenital anomalies, umbilical cord prolapse, birth injury, intrapartum/neonatal death Results One percent (n = 695) of individuals experienced breech birth (n = 401, 57.6% vaginally). Most fetuses presented frank breech (57%), with 19% complete, 18% footling/kneeling, and 5% unknown type of breech presentation. Among all breech labors, there were high rates of intrapartum transfer and cesarean birth compared to cephalic presentation (OR 9.0, 95% CI 7.7–10.4 and OR 18.6, 95% CI 15.9–21.7, respectively), with no substantive difference based on parity, planned site of birth, or level of care integration into the health system. For all types of breech presentations, there was increased risk for nearly all assessed neonatal outcomes including hospital transfer, NICU admission, birth injury, and umbilical cord prolapse. Breech presentation was also associated with increased risk of intrapartum/neonatal death (OR 8.5, 95% CI 4.4–16.3), even after congenital anomalies were excluded. Conclusions All types of breech presentations in community birth settings are associated with increased risk of adverse neonatal outcomes. These research findings contribute to informed decision-making and reinforce the need for breech training and research and an increase in accessible, high-quality care for planned vaginal breech birth in US hospitals.

Abstract:

Background Cervical dilatation curves are widely used to describe normal and abnormal labor progression for cephalic presentation. Labor curves for breech presentations have never been described. Objectives The aims of this study were to examine the pattern of labor progression in women with a breech presentation and to determine whether the type of breech or parity can influence the speed of cervical dilatation. Study design We analyzed the labor data from 349 women with a term, singleton, and breech fetus after spontaneous onset of labor in 2010–2018. Cesarean deliveries were excluded. The patterns of labor progression were described by examining the relationship between the elapsed times from the full dilatation and cervical dilatation stages. Average labor curves were developed using repeated-measures analysis with 3rd degree polynomial modeling. The results were interpreted according to parity and the type of breech. Results The first stage of labor progression was divided into a latency phase from 0 to 5 cm of dilatation and an active phase from 5 to 10 cm. In the active phase, the median speed of cervical dilatation was 1.67 cm/h [1.25, 2.61] (2 cm/h for multipara and 1.54 cm/h for nullipara). The difference by parity was significant in the active phase (p< 0.05). The cervical dilatation rate from 3 cm to 10 cm did not significantly differ between the complete and frank breeches (1.56 cm/h vs 1.75 cm/h, p = 0.48). However, the median cervical dilatation rate from 8 cm to complete dilatation was faster for complete breeches (1.92 cm/h versus 1.33 cm/h, p = 0.045). Conclusion As with cephalic presentation, the first stage of labor progression for breech presentation can be divided into a latent and active phase. Labor progression should be interpreted with respect to parity, and women should be informed that the type of breech does not seem to influence the cervical dilatation rate when there is adequate management.

Abstract:

The Breech Baby Study is a mixed methods study which combines qualitative and quantitative inquiry. This study explores psycho-social-cultural risk factors for breech presentation from an evolutionary perspective. The quantitative component of the study uses Florida birth certificate and Medicaid data sets from 1992-2003 to evaluate the influence of ethnicity and socio-economic status on breech presentation. Ethnicity and socio-economic status account for less than two percent of the variance of risk factors for breech presentation. The qualitative study includes 114 mothers of breech and cephalic presentation babies who completed the State Trait Personality Inventory and a socio-demographic survey. Of these, 52 mothers of cephalic presentation babies and 23 mothers of breech presentation also participated in an in-depth interview about formative life experiences and peri-conception through delivery. The primary data analysis found mothers of breech presentation babies exhibit psycho-social-cultural characteristics unlike those found in mothers of cephalic presentation babies. These characteristics include being idealistic, analytical, polished, overextended, and fearful. Mothers of cephalic presentation babies were better equipped to adapt to unexpected situations and to be pragmatic in the face of unresolvable circumstances. Mothers of breech presentation babies were further separated into two categories. One category is achievement focused woman while the other is non-present focused woman. While both sets of breech presentation mothers were idealistic, the achievement focused mothers were more likely to be analytical, polished, and overextended. In contrast, the non-present focused mothers had a history of abuse and were more likely to have an unresolved pregnancy outcome or to be fearful. Breech presentation is interpreted by attachment theory, evolutionary ecological reproductive theory, and developmental plasticity theory as a fetal strategy to adapt to the intra-uterine relationship environment and an attempt to predict the extra-uterine relationship environment.

Abstract:

Includes bibliographical references.
Background External Cephalic Version (ECV) is the manipulation of the baby, through the mother’s abdomen to a cephalic presentation. ECV is typically performed antenatally, in women with a breech presentation who are not in labour, at or near term, to improve their chances of having a normal vaginal delivery. ECV is one of the few obstetric interventions for which there is evidence that its use leads to a fall in caesarean section rates. ECV is an intervention that gives women another option, prior to considering caesarean section. Objective: To evaluate whether there were missed opportunities for performing ECV in women that had caesarean sections for breech presentation at term, and to determine the reasons why ECV was not offered or attempted for women with breech presentation, who had a caesarean section for that reason.

Abstract:

Breech presentation affects 3-4% of women pregnant with a single baby after 37 weeks of pregnancy. These women face two key decisions: firstly, whether or not to attempt to turn their baby by external cephalic version (ECV). Secondly, if they decide not to attempt this, or it is unsuccessful, then they need to decide how to give birth to their baby, either by planned caesarean section (CS) or vaginal breech birth (VBB). This thesis explores the process of decision making about breech presentation from both women’s and health professionals’ perspectives and documents the development of a patient decision aid (PDA), consisting of an animated film and website, for women facing these decisions in the future. In this qualitative study, data were collected using observed consultations, semi-structured interviews, with both women and professionals, and user-centred design workshops. Thirty nine women and 30 health professionals were respondents. Data were analysed using constant comparison. The results show that the diagnosis of breech presentation often comes late in pregnancy and begins with uncertainty, partly because many professionals are reluctant to provide information about options until the diagnosis is confirmed by ultrasound examination. Professionals are concerned about causing unnecessary anxiety to women who do not have a breech presentation confirmed, but such an approach fails to take account of women’s clear preference for information as soon as the possibility of breech presentation is raised. Women report researching options online and amongst their social contacts, as they strongly value experiential accounts. However they may struggle to find trustworthy information from these sources as they are frequently told horror stories. Women may also be directively counselled by professionals who have a clear preference for attempting ECV. In response to these themes, a PDA was developed which is freely available to women and includes a website summarising the evidence about the different options. In relation to decision making, women described five key values: wanting to keep their baby safe; wanting to experience a natural birth and to breastfeed; preferring to avoid surgery; needing to be able to care for other children; and wanting to have control. Postnatally, they shared vivid accounts of their experiences of ECV and birth, which were used to inform the script for the animated film that aims to provide the experiential information women wanted and also help them to explore their own values about decision making.

Abstract:

Background: The incidence of caesarean section for breech presentation has reached approximately 90 % in Sweden. In many of these cases, by means of specific selection criteria, it would be as safe to plan for vaginal breech delivery. Aim: The objective of this study was to investigate differences in management and to compare maternal and fetal outcomes according to delivery mode of breech presentation; vaginal vs. caesarian section. The study included breech presentation in full term singleton pregnancies at the UppsalaUniversityHospital, Uppsala, Sweden (UAS). Method: The study was based on medical record data with a retrospective, descriptive, comparative design with quantitative approach. The method for data collection was a manual review of patient records using a structured questionnaire. Results: Of the women with children in breech presentation during the period studied, 11 % gave birth vaginally. Mother's wish was the most common cause of caesarean section. The group with caesarean section included more first-time mothers, longer length of stay at the hospital, increased bleeding and need for pain medication, separation from the child, later lactation and earlier introduction of formula. Vaginally delivered mothers had increased incidence of straight urine catheterization postpartum and of infants with lower Apgar scores. Conclusion: This study does not support the suggestion that it would be safer to give birth by caesarean section for breech presentation in cases where the woman at full term meets strict selection criteria. Instead of applying medical criteria, the decision regarding mode of delivery was more often left up to the mother.

Abstract:

Breech presentation creates division in the consumer and healthcare communities. A number of studies report the use of scare tactics and bullying from clinicians, when women express a preference for vaginal birth after the diagnosis of a breech presenting fetus. Despite evidence showing that vaginal birth of a breech presenting fetus is safe in the presence of an appropriately skilled and experienced clinician, Caesarean Section is the primary mode of birth for breech presenting fetuses, which has resulted in a global lack of accessibility to breech birth experienced practitioners and birth mode options for women. Women planning a vaginal breech birth in a maternity care system, where the occurrence of this phenomenon is rare, face multiple challenges. Little is known of women’s breech pregnancy and birth experiences in Western Australia (WA). A mixed methods study involving semi-structured interviews, a multinational electronic Delphi (e-Delphi) study and clinical practice guideline review was designed to explore breech presentation from the perspective of women in Western Australia, and professionals with knowledge and/or experience of caring for women with a breech presenting fetus. The clinical practice guideline review provides insight into the parameters women with a breech presenting fetus planning a vaginal birth have to work within. For the clinical guideline review, clinical practice guidelines were purposively sought from leading obstetric organisations and reviewed using the International Centre for Allied Health Evidence (iCAHE) appraisal checklist. Key consistencies and inconsistencies between the guidelines were identified. Varying levels of evidence are used to support the recommendations made by professional organisations. The inconsistencies highlighted in the review have the potential to create confusion among clinicians and women and to cause issues related to valid consent, further emphasising the importance of balanced information and universal definitions for variations such as a footling presentation. The women’s aspect of this study illustrates the experiences of some women in WA. Critical theoretical concepts of knowledge and power as described by Michel Foucault, were used to describe power relations noted during clinical interactions between women and their care providers. These findings were consistent with previous reports of coercion and bullying when women’s preferences conflicted with those of their care provider. Also identified were five distinct phases women experienced throughout their breech experience – Reacting, Information, Bargaining, Decision Making and Acceptance - which showed some similarities to the Kübler-Ross model of grief. Combining the Five Stages of Breech and Foucauldian concepts of knowledge and power facilitated the identification of areas in practice which need improvement. Midwives were seen as supportive navigators of a restrictive system. The multinational e-Delphi study explored the panel’s knowledge views and recommendations of care for breech presentation. The main findings of this aspect of the study were the Breech Care Pathway provided in a midwifery-led multidisciplinary continuity of care model, a clinical skills development and maintenance framework and the proposal of a standard definition for a footling breech presentation. Providing woman-centred care in a midwifery – led multidisciplinary continuity of care model has the potential to improve the experiences and health outcomes for women and their babies. While continued improvement is needed, steps are being undertaken, particularly by midwives, to facilitate women’s autonomy and support their birth preferences. This thesis highlights current obstacles faced by women and clinicians in relation to breech presentation in contemporary maternity care. It suggests multiple ways in which this may be achieved and provides pathways and frameworks which may be used to support this process.

Thesis (MMed)-- Stellenbosch University, 2013.
ENGLISH ABSTRACT: AIM: Review outcome of pregnancies following successful external cephalic version (ECV) for breech presentation at term, particularly the caesarian section (CS) rate. ECV is a safe procedure with a minimal cost implication that can reduce non-cephalic presentation at onset of labour at term. The outcome of pregnancies following successful ECV is certainly of interest. A meta analysis of studies done between 1997 and 2004, found that pregnancies after successful ECV at term were not the same as those with spontaneous cephalic presentations and was associated with a CS rate twice that in pregnancies with spontaneous cephalic presentations. The conclusion was that pregnancies after successful ECV should not be considered the same as normal pregnancies. In a matched retrospective analysis of CS risk after successful ECV, done in the USA, it was concluded that CS delivery and operative vaginal delivery rates following successful ECV, were not increased. To date there are no such studies in South Africa. METHODOLGY: A retrospective descriptive study was done to audit all successful ECV’s done at the Fetal Evaluation Clinic (FEC) of Tygerberg Academic Hospital. The electronic data from the FEC was searched for successful ECV patients. The facilities where these patients delivered were identified. The outcome of the pregnancies was determined from patient files and/or the labor registers. The relevant information of each patient was captured. All file reviews and data capturing was done by the principal investigator. RESULTS: A total of 78 patients were included in the study. The median age was 28.7 years with a range from 17 to 40 years, the median parity 1 and the range 0 to 6 and the median body mass index 27.2 and the range 18.2 to 45.0. The method of determining gestational age is known in 71 (91%) patients of whom 37 (52%) had an early ultrasound examination. The median gestational age at ECV was 37 weeks with the inter quartile range 36 to 38 weeks. The median ECV to delivery time was 2 weeks with the inter quartile range 1 to 4 weeks. Higher levels of care were required at time of delivery by 47 (60.3%) patients. Vaginal deliveries occurred in 49 patients and 29 (37.2%) had CS. The most common indications for CS were cephalo pelvic disproportion 8, fetal distress 6, reversion back to breech presentations 4 and other abnormal presentations 4 (2 face presentations and 2 transverse lies). The mean birth weight of the babies was 3360g and the range 2100 to 4655g. On comparing the groups that had vaginal deliveries and CS, only nulliparous patients had a significantly (p=0.02) higher risk for CS. CONCLUSIONS: Following successful ECV all patients need to be carefully followed up for possible reversion to breech presentation or transverse lie. Nulliparous and gravid 2 para 1 patients with a previous CS need to be delivered in hospitals with CS facilities. Further studies are required to assess whether successful ECV results in more face presentations.
AFRIKAANSE OPSOMMING: DOELWIT: Om die uitkoms van swangerskappe na suksesvolle eksterne kefaliese kerings (EKK) vir stuit presentasies op voltyd, spesifiek die keisersnit (KS) insidensie te bepaal. EKK is ‘n veilige prosedure wat teen minimale koste die nie-kefaliese presentasies op voltyd kan verminder. Die uitkoms van swangerskappe na suksesvolle EKK is van belang. ‘n Meta-analise van studies gedoen tussen 1997 en 2004 vind dat swangerskappe na suksesvolle EKK op voltyd nie dieselfde is vergeleke met spontane kefaliese presentasies nie en gepaard gaan met ‘n KS koers tweekeer hoër as dié met spontane kefaliese presentasies op voltyd. Die gevolgtrekking was dat swangerskappe na suksesvolle EKK nie as normale swangerskappe beskou moet word nie. In ‘n gepaarde retrospektiewe ontleding van die KS risiko wat in die VSA gedoen is, word gevind dat die KS en operatiewe vaginale verlossing koerse na suksesvolle EKK, nie verhoog is nie. Tot op hede is daar geen studies hieroor in Suid-Afrika gedoen nie. METODE: ’n Retrospektiewe beskrywende studie is gedoen om all suksesvolle EKK wat by die Fetale Evaluasie Kliniek (FEK) gedoen is te oudit. ‘n Elektroniese data soektog van suksesvolle EKK by die FEK is gedoen. Die instellings waar die pasiënte verlos is, is vasgestel. Die uitkoms van die swangerskappe is bepaal deur pasiënt lêers en/of die kraamregisters na te gaan. Die relevant inligting oor elke pasiënt is versamel. RESULTATE: ‘n Totaal van 78 pasiënte is by die studie ingesluit. Die mediane ouderdom was 28.7 jaar met ‘n reikwydte van 17 tot 40 jaar, die mediane pariteit was 1 met ‘n reikwydte van 0 tot 6 en die mediane liggaamsmassa indeks 27.2 met ‘n reikwydte van 18.2 tot 45.0. Die metode waavolgens swangerskapsduurte bepaal is, was bekend in 71 (91%) van pasiënte, waarvan 37 (52%) vroeë ultraklank ondersoeke gehad het. Die mediane swangerskapsduurte tydens die EKK was 37 weke met die interkwartiele interval 36 tot 38 weke. Die mediane EKK tot verlossing tydsverloop was 2 weke met die interkwartiele interval 1 tot 4 weke. Hoër vlakke van sorg was nodig ten tye van die verlossing by 47 (60.3%) van pasiënte. Van die pasiënte het 49 vaginale verlossings en 29 (37.2%) KS gehad. Die mees algemene indikasies vir KS was skedel-bekken disproporsie 8, fetale nood 6, terugkeer na stuitpresentasie 4 en abnormale presentasies 4 (2 aangesigsliggings en 2 transversliggings). Die gemiddelde geboorte gewig van die babas was 3360g en die reikwydte 2100 tot 4655g. Wanneer die groep wat vaginale verlossing en KS gehad het vergelyk word, het slegs nullipareuse pasiënte ‘n betekenisvolle (p=0.02) hoër risiko vir KS gehad. GEVOLTREKKING: Na suksesvolle EKK moet alle pasiënte noukeurig opgevolg word vir terugkeer na ‘n stuit presentasie of transversligging. Nullipareuse en gravida 2 para 1 pasiënte met ‘n vorige KS moet in hospitale met KS fasiliteite verlos word. Verdere studies is nodig om te bepaal of suksesvolle EKK meer aangesig presentasies tot gevolg het.

Abstract:

Preterm labour is a common cause of neonatal morbidity and mortality. This chapter describes the definition, aetiology, diagnosis, and management of preterm labour and delivery with a focus on tocolytic therapy, the use of antenatal corticosteroids, and of magnesium sulphate. Anaesthesia for preterm delivery is discussed. The section on multiple pregnancy details the recommended antenatal careplan for dichorionic and monochorionic twin pregnancies, the fetal and maternal risks and potential complications, and the management of labour and delivery of twins, as well as the anaesthetist’s role in managing these high-risk pregnancies. There are a number of abnormal presentations managed by obstetricians, including abnormal cephalic presentations such as occiputo-posterior positions, breech, transverse, and compound presentations. This chapter focuses specifically on breech presentation, comparing the evidence for vaginal breech delivery versus planned caesarean delivery. It also discusses external cephalic version and vaginal breech delivery itself.

Abstract:

AbstractThis chapter aims to encapsulate the core elements of the keynote presentation on experience and interaction designs, primarily those using augmented reality, virtuality, or a mix of physical and digital elements. My interest is not in creating cutting-edge technology, but rather in seeing how people react, engage, think, move, and feel when they engage with designs by myself and colleagues.The contribution I make is to use performance theories and practices in design, especially design for mixed reality experiences, so that I can bring specific tools to bear on the creation and analysis of those designs. ‘Performance’ can be the kind practiced by professionals. It can also be the behaviours of people who take on the role of audience member or bystander. It can also be ‘performance’ in the ways that people ‘perform’ their everyday lives.Performance often aims to be thought-provoking, but (aside from Bertolt Brecht and those who use his politically minded Verfremdungseffekt) it virtually always aims for an emotional response through engagement with the aesthetic choices that have been made. This chapter provides a basic theoretical grounding and a specific example of how performance can lay out a richer design space for personally meaningful experiences.

Abstract:

The current trend in offshore drilling is a significant increase in water depth in the specification of drilling risers, associated with high density muds. This situation presents a real challenge for the design of the drilling riser which depends to a large extent on these parameters, as well as other related to operational and environmental conditions. In particular, improved design methodologies are required to better assess the margins of riser couplings regarding their static performance and fatigue life. As recommended by API Spec 16R, the stress linearization and classification in one of the key steps to design a riser connector. The designers are encountering some difficulties in the application of this methodology to 3D finite element results. IFP has then proposed a simple approach that applies to non-axisymmetric geometries of connectors. It consists in calculating the membrane and bending stresses in a given plane by averaging over a suitable portion of a cross-section the results of the linearization in the stress classification lines (SCLs) located in the selected plane. A short presentation of a breech-block type riser connector, on which the methodology has been applied, is given at the beginning of this paper. The API specification 16R requirements regarding the design criteria are then discussed. A simple approach to extend the stress linearization and classification methods to three-dimensional FEA is proposed. The proposed methodology is applied to the design of the Clip connector. At last, the R&D work aiming at improving the fatigue analysis of riser connectors is introduced at the end of the paper.

Abstract:

Whilst blood is the sample most often collected for diagnostic purposes, testing is complicated by the need to purify or concentrate biomarkers prior to detection. While needle/syringe or lancet technology is most often used for bulk sample collection, devices have not yet been developed that selectively capture biomarkers of interest in vivo, simplifying downstream detection requirements. Our group developed the Micropatch Array — a device comprising an array of microprojections which breach the outer layers of the skin to selectively capture biomarkers from the dermis. In this presentation we will describe our emerging data focused on the mechanisms of biomarker capture in vivo, and our investigations into improving the capture efficiency of the devices for important biomarkers.

Abstract:

Identifying security properties raises a laborious analysis within the design of a software system. Some tools help model security concepts, others test and validate results. The article introduces an introduction to the software used to design security systems, especially in the sphere of hierarchical security modelling encountered in organizations. An analysis of the design and modelling tools from the perspective of security requirements and the adjacent principles of interest is presented. As there is no clear separation between design errors and security deficiencies, there are some design practices that lead to a security breach. Obviously, some design methods generate more insecurity than others, which is why the tools are presented from the perspective of vulnerability modelling, cryptography, security protocols, and risk management. The use of security-oriented tools guarantees the availability of functionality, does not guarantee by this functionality the security itself, because they are specialized in certain areas of application and abstraction The aim of this paper is the ontology development for multiple personalized security system approaches in order to adapt a suitable domain ontology according to hierarchical security systems policies and to satisfy the future requirements of users and promote the use value. To answer at “How efficiency is the proposed Hierarchical Ontology?”, a domain ontology model is designed and a methodology for domain ontology adaptation is developed. Subsequently, a domain ontology adaptation system is implemented based on organizational security culture key factors. The article ends with the presentation of a few questions that an instrument designed for the hierarchical security of an organization needs to answer.

Abstract:

The self-organization of matter has been extensively explored in recent years, and significant advancements have been made in the field of porous ordered films produced by the auto-assembly of different polymer materials, being block of copolymers, blends of homopolymers or amphiphilic polymers. The hierarchical ordering in micro-organized films, known also as Honeycomb (HC) structure, generates a significant increase of specifics characteristics enhancing certain properties of the materials. The preparation of self-assembled porous membrane is done by different approaches. We use hereby the bottom-up microporous structuring method specifically the breath figure (BF) approach to prepare highly-organized membrane from polymer blends. The foremost motives for using the BF are the simplicity of implementation and the adaptability to multiple systems which make it a robust and inexpensive technique for the production of structured surfaces. The honeycomb (HC) structures formed by the BF is a potential candidate for water treatment as a filtration membrane to treat stable oil-water emulsions encountered in the oil and gas industry. The use of homopolymer blends improves the selectivity, permeability and anti-fouling properties comparing to the commercial homopolymer membrane. This presentation will highlight the preparation of self-assembled blends of homopolymers membrane by BF and their performance for cleaning of industrial wastewater and the fouling/re-use potential.

Abstract:

Although the internet has made a plethora of resources accessible to many, those resources are inadequately protected at Saudi universities. Some students and instructors use electronic material, software, Apps, Powerpoint presentations, articles, research papers, ebooks, video clips and/or images that they like or find useful in the online learning environment without documentation and without seeking the owner's permission. This study investigates the availability and awareness of intellectual property rights of electronic material and resources at Saudi universities and report students and instructors' views on the infringement of intellectual property, reasons for infringements, and misconceptions of proper use. Interviews with a sample of students and faculty have shown that many students are unaware of intellectual property rights and laws. There is a great need for protecting the copyright of electronic materials at Saudi universities. Saudi Universities need to have clearly stated Intellectual property laws that protect and encourage the creation and proper use of electronic materials and resources by students and faculty. Findings also revealed some misconceptions about plagiarism and improper use of electronic resources. Some believe that it is their right to use online resources. Others refuse to delete what they have illegally used as they feel that they have not breached any laws. Some faculty were exposed to the illegal use of their online material, but they do not know where they can complain to regain their copyright. Others indicated that when they complained, their institutions did not care about protecting their copyright and punishing those who breach copyrights; in addition to the negative effects of plagiarism on faculty morale and productivity. Results will be reported in detail.
